Itsuki, Nayuta, and Miyako have a hard time dealing with the cold and head down to Okinawa. The next day, they visit a remote island so Itsuki can do some research and Nayuta decides to flail around naked in the water. Miyako is awed by what she's seeing and eventually jumps into the water naked, as well. Two days later, Itsuki is invited by his illustrator to go to Hokkaido, where they try various local cuisines. However, Itsuki finds out that Setsuna had been ignoring a deadline...
Whale Shark
The largest species of fish currently 
living. They eat plankton and small fish, 
and they pose little danger to humans. 
A whale shark's giant body cruising 
through the water is a mesmerizing sight.

[Squalo balena]

La più grande specie vivente 
di pesce. Mangiano plancton e piccoli pesci
 e rappresentano una minaccia minima 
per gli umani. Uno squalo balena che 
nuota nell'acqua è una visione incantevole.

Китоая акула:
Крупнейшая из живущих в наши
дни рыб. Питается в основном
планктоном. Плавает медленно
и спокойно, а потому не несёт
никакой угрозы для человека.
Её крупная фигура, степенно
рассекающая морскую гладь
буквально завораживает.
